Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline cleaning, and more specifically, relates to a blowing device for industrial pipeline construction. Background Art

[0002] During the construction of industrial metal pipeline projects, it is necessary to remove the dust inside the pipeline for subsequent construction. Airflow blowing can better remove the dust attached to the inner wall of the pipeline.

[0003] Based on the above, the purging device currently used uses a pressure difference method for purging. For example, the patent with application number CN202222279314.2 discloses an industrial metal pipeline blasting and purging device, which includes an end pipe and an electric ball valve. The front end of the end pipe is connected to the end of the industrial metal pipeline, the first port of the electric ball valve is connected to the end of the end pipe, the side wall of the end pipe is connected to the gas source through a pressure pipe, and a solenoid valve for controlling the gas input is provided on the pressure pipe. A pressure sensor for detecting the gas pressure in the pipeline is provided in the end pipe. The electric ball valve and the pressure sensor are connected to the DSP control system. When the dust does not meet the cleanliness requirements, gas is injected into the pipe to increase the pressure. When the set pressure is reached, the electric ball valve is controlled to open. The high-speed ejected airflow and the resulting pipeline vibration bring out the welding slag and other debris in the pipeline. The electric ball valve plays the role of replacing the blasting plate.

[0004] The purging method using pressure difference still cannot guarantee the purging effect of the airflow, there are ventilation gaps, and it is inconvenient to make the airflow flow along the inner wall of the pipe for purging. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a blowing device for industrial pipeline construction to solve the problem that the blowing method using pressure difference proposed in the above background technology still cannot guarantee the blowing effect of the airflow, there are ventilation side seams, and it is inconvenient to make the airflow flow along the inner wall of the pipeline for blowing.

[0006] The purpose and effect of the purge device for industrial pipeline construction in this utility model are achieved by the following specific technical means:

[0007] A blowing device for industrial pipeline construction includes a mobile machine, wherein the external part of the mobile machine is hingedly provided with three rows of long connecting rods, and the middle part of the long connecting rods is hingedly provided with a short connecting rod; the rear end of the mobile machine is fixedly provided with an electric cylinder, and the telescopic end of the electric cylinder is hingedly connected to the short connecting rod; the outer end of the long connecting rod is hingedly provided with a side bracket, and both ends of the side bracket are rotatably provided with a traveling wheel driven by a micro motor; the front end of the mobile machine is fixedly provided with an air control device, and the front and rear sides of the external part of the air control device are fixedly provided with two groups of spacer rings, and an annular air bag is fixedly provided between the two adjacent groups of spacer rings; two groups of connecting air rings are fixedly provided on the external part of the air control device, and an air extraction ring is also fixedly provided between the rear connecting air ring and the spacer ring; the bottom of the air control device is connected with an air pump; and wrapping rings are fixedly provided outside the two middle groups of spacer rings.

[0008] Furthermore, the front and rear sides of the annular airbags are both corrugated structures; the two groups of annular airbags are each connected to a group of connecting air rings through a pipeline.

[0009] Furthermore, the bottom of the connecting air ring is connected to a solenoid valve A, which is connected to the output port of the air pump.

[0010] Furthermore, a pipeline is provided inside the air extraction ring and passes through the air control device to be connected to an air intake ring, and the air intake ring is sleeved on the outside of the mobile machine.

[0011] Furthermore, the input port of the air pump is connected to the air extraction ring through a pipeline.

[0012] Furthermore, the outlet of the air pump is also connected to a solenoid valve B, which is communicated with the wrapping ring; and a forward-inclined injection port is arranged around the outside of the wrapping ring.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] An annular airbag is provided to provide a closed purging function. The rear annular airbag is expanded and the side of the annular airbag is used to fit the inner wall of the pipe for sealing. The front annular airbag is also inflated, and the side of the annular airbag is brought close to the inner wall of the pipe but not fitting it, which can increase the pressure. Air is input into the wrapping ring and ejected from the injection port for purging, which can make the airflow fit the inner wall of the pipe for high-pressure purging.

[0015] In addition, two sets of annular airbags can be used for pressure difference cleaning. The two sets of annular airbags are inflated at the same time, and then the interior of the rear annular airbag is pressurized separately so that the diameter of the rear annular airbag is larger than that of the front annular airbag. This can generate a pressure difference and ensure that the airflow moves forward. Then, the device is moved forward to perform mobile blowing.

[0016] The injection port can be used for mobile blowing. Place the device in the pipeline, retract the electric cylinder, and use the short connecting rod to drive the long connecting rod to rotate outward, open the three sets of side brackets, and use the traveling wheels to fit the inner wall of the pipeline for centering. Ensure that the traveling wheels are set in the center, and use the motor to drive the traveling wheels for automatic movement. The use of connecting rod drive can provide adaptability and is suitable for mobile blowing of pipelines of different sizes. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples.

[0025] Example 1:

[0026] As attached Figure 1 To the attached Figure 5 As shown:

[0027] The utility model provides a blowing device for industrial pipeline construction, comprising a mobile machine 1, the outside of the mobile machine 1 is hingedly provided with three rows of long connecting rods 101, and the middle of the long connecting rods 101 are hingedly provided with short connecting rods 102; the rear end of the mobile machine 1 is fixedly provided with an electric cylinder 2, and the telescopic end of the electric cylinder 2 is hingedly connected to the short connecting rod 102; the outer end of the long connecting rod 101 is hingedly provided with a side bracket 103, and both ends of the side bracket 103 are rotatably provided with a traveling wheel 104 driven by a micro motor; the front end of the mobile machine 1 is fixedly provided with an air control device 3, the front and rear sides of the outside of the air control device 3 are fixedly provided with two groups of spacer rings 4, and an annular air bag 5 is fixedly provided between the two adjacent groups of spacer rings 4; two groups of connecting air rings 6 are fixedly provided on the outside of the air control device 3, and an air extraction ring 7 is also fixedly provided between the rear connecting air ring 6 and the spacer ring 4; the bottom of the air control device 3 is connected with an air pump 8; the two middle groups of spacer rings 4 are fixedly provided with a wrapping ring 9.

[0028] The front and rear sides of the annular airbags 5 are both corrugated structures; the two groups of annular airbags 5 are each connected to a group of connecting air rings 6 through a pipeline.

[0029] Among them, the bottom of the air ring 6 is connected to a solenoid valve A601, and the solenoid valve A601 is connected to the output port of the air pump 8.

[0030] A pipeline is arranged inside the air extraction ring 7 and passes through the air control device 3 to be connected to the air intake ring 701 . The air intake ring 701 is sleeved on the outside of the mobile machine 1 .

[0031] The input port of the air pump 8 is connected to the air pumping ring 7 through a pipeline.

[0032] Among them, the outlet of the air pump 8 is also connected to a solenoid valve B801, which is communicated with the wrapping ring 9; and a forward-inclined injection port 901 is arranged around the outside of the wrapping ring 9.

[0033] like Figure 1-5 As shown, the device is placed in the pipeline, the electric cylinder 2 is retracted, and the long connecting rod 101 is driven to rotate outward with the cooperation of the short connecting rod 102, and the three sets of side brackets 103 are opened. The traveling wheel 104 is used to fit the inner wall of the pipeline for centering, ensuring that the traveling wheel 104 is set in the center, and the traveling wheel 104 is driven by the motor to move automatically; the solenoid valve A601 connected to the rear side connecting air ring 6 is opened, and the air pump 8 is started. Air is extracted through the air intake ring 701, and the air enters the air intake ring 701, passes through the air extraction ring 7 and the air pump 8, and is input into the rear side connecting air ring 6, and then enters the rear side annular airbag 5 to expand the rear side annular airbag 5, and the side of the annular airbag 5 is used to fit the inner wall of the pipeline for sealing, and then the rear side solenoid valve A601 is closed;

[0034] Open the solenoid valve A601 connected to the front air ring 6, inflate the front annular airbag 5, and bring the side of the annular airbag 5 close to the inner wall of the pipe but not in contact with it. At this time, close the solenoid valve A601 and open the solenoid valve B801 to input air into the wrapping ring 9 and eject it from the injection port 901 to perform purging. The airflow can flow in contact with the inner wall of the pipe, and high-pressure purging can be performed.

[0035] A pressure sensor can be set inside the annular airbag 5 to monitor the pressure;

[0036] It is necessary to set an automatic moving program. Each time the positioning and purging is performed, the two groups of annular air bags 5 are contracted to move the device forward. The length of each movement is consistent with the length of the air control device 3, and cyclic purging can be achieved.

[0037] Example 2:

[0038] On the basis of Example 1, the two groups of annular airbags 5 can be used for pressure difference cleaning. The two groups of annular airbags 5 are inflated at the same time, and then the interior of the rear annular airbag 5 is pressurized separately, so that the diameter of the rear annular airbag 5 is larger than that of the front annular airbag 5. This can generate a pressure difference to ensure that the airflow moves forward. Then, the device is moved forward to perform mobile purging.

[0039] If there is a lot of dust in the pipe, you can choose to use pressure difference to blow it out first, and then close it for cleaning.

[0040] The specific usage and function of this embodiment are as follows:

[0041] In the present invention, the device is placed in the pipe, the electric cylinder 2 is retracted, and the short connecting rod 102 is used to drive the long connecting rod 101 to rotate outward, thereby opening the three sets of side brackets 103. The traveling wheels 104 are used to fit the inner wall of the pipe for centering. The traveling wheels 104 are ensured to be centered, and the motor is used to drive the traveling wheels 104 to move automatically.

[0042] Open the solenoid valve A601 connected to the rear connecting air ring 6, start the air pump 8, and extract air through the air inlet ring 701. The air enters the air inlet ring 701, passes through the air extraction ring 7 and the air pump 8, and is input into the rear connecting air ring 6. Then, the air enters the rear annular airbag 5 to expand the rear annular airbag 5. The side of the annular airbag 5 is attached to the inner wall of the pipe to seal it. Close the rear solenoid valve A601.

[0043] Open the solenoid valve A601 connected to the front air ring 6, inflate the front annular airbag 5, and bring the side of the annular airbag 5 close to the inner wall of the pipe but not close to it. At this time, close the solenoid valve A601, open the solenoid valve B801, input air into the wrapping ring 9, and spray it out from the injection port 901 to perform purging. It can make the airflow flow along the inner wall of the pipe for high-pressure purging. Set the automatic travel program, and each positioning purge will retract the two groups of annular airbags 5 to move the device forward. The length of each travel is consistent with the length of the air control device 3, and cyclic purging can be achieved.
